ION-SOLVENT INTERACTIONS IN SYSTEMS - PROPYLENE CARBONATE-NITROMETHANE

Solvation process in the mixed solvent propylene carbonate-nitromethan e was investigated. The equivalent conductivity and association consta nts of ions were measured and evaluated for the following electrolytes : Bu4NBPh4, NaBPh4, Bu4NI, Bu4NCIO4, Et4NCIO4, Et4NPi, KI, LiCIO4, Me4 NPi, Bu4NBr, and Et4NCI. The conductance viscosity products were analy sed and parameters of the maximum approach of the ions were determined . The results suggest that nitromethane, unlike propylene carbonate, e xhibits a less pronounced tendency to solvate the ions in the solvent system studied.
